PI
PI material, (chemically known as Polyimides) is a non melting high temperature polymer. Strength, dimensional stability, and creep resistance remain high even at temperatures above 260°C. Low wear rates combined with the ability to work under unlubricated conditions and high pV-rates makes it the ideal material for challenging friction and wear applications, extending lifetime and reducing maintenance costs. Its high purity and low outgassing are needed for applications in the vacuum, space and semicon industry.PI plastic is a non melting high temperature polymer.
